This symbol represents "good fortune" and "well being" and as well as "good luck" it represents Aryan identity, Germans national pride. The Nazi used this symbol as their own because it conjected the Aryan culture had decent the people of German. So I believe this symbol was important to the people.
From What I believe that is important was how Jews weir punished nor beat if they didn't wear the star. if the people refused to wear this symbolic badge they would be killed.
